What effect does having a baby have on your relationship?
This is really hard to know, to be honest. You will both be stressed out, tired and also trying to figure out how your relationship and parenting can go hand in hand.
It's not easy. Just being honest.
The thing is, you will see your partners strengths and weaknesses during this time. It is how you learn how you work together, which may be that you work together very well! It may give you a further appreciation for each other too which can make your bond even stronger.
